' VICTOR HUGLO, OF LILLE, FRANCE.

HACKLING-MACHINE.

To all whom it may concern.

Be it known that I, Vroron Home, a citizen of the French Republic,andresident of Lille, France, have invented certain new and usefulImprovements in Hackling- Machines, of which the following is aspecification.

This invention relates to hackling machines of the type adapted for usewith flax,

hemp or the like, and has for its primary object the provision ofmechanism of the character set forth which shall overcome many of thedifficulties inherent to such machines.

A further object of this invention is to provide improved holders forsuch machines more particularly adapted for efficient use and operation.

A still further object is to provide simple and positive operating meansfor opening the holders carrying the flax.

A further object is to provide mechanism for tightening the holders andmeans for closing the said holders.

A still further object is to provide a flax or hemp hackling machine ofthe character described having mechanism for turning overthe holders andsecuring a continuous movement of the holder through the machine, withthe minimumrof attention and maximum of efliciency.

With these and other objects in view the invention consists in thepeculiar arrangement and combination of the various parts of a hemp orflax hackling machine as hereinafter described and more particularlypointed out in the appended claims.

The holders for hemp and fiax hackling machines are formed by two platesguided on each other one of.,which, the bottom plate carries secured inits center a screw which passes through a corresponding hole provided inthe center of the other plate, the lid, the said screw being adapted toreceive a tightening nut. The well known automatic screwing mechanismshave for their object to unscrew mechanically the said nut to remove'thelid of the holder in order to allow of the latter being refilled, toreplace Specification of Letters Patent. Application filed February 18,1913. Serial N 0; 749,258.

fiber. The holders mentioned above have numerous drawbacks. They do notallow of the surface of their plates being completely made use of owingto the bolt pass through the center of the latter. The operator whenfilling the holder with fiber forms a greater thickness of hemp or offlax around the central screw, for the central fibers which have beendeflected from the rectilinear direction are piled up on each side ofthe screw and the traction exerted upon the pieces when the latter arechanged or shifted, strains the fibers. The poor distribution of thefiber produces an objectionable grip whatever the power of the latter.The tendency is to use longer and longer holders but this tendencyreduces the efliciency of the grip; the good holding of the fiberdecreases more and more from the center 2'. e. from the screw up to bothends of the holder where it is the less sure as the defects in thetightening due to the causes mentioned above are multiplied there by thelength of the holder.

The automatic screwing mechanisms coopcrating with the screw holders areextremely complicated and very expensive. They are subjected to numerousbreaks of parts, interruptions in their work so that they require thecontinuous and attentive attendance of a good mechanic, thus materiallyincreasing the cost of operation of the machine.

The automatic screwing devices are always mounted on a pair of hacklingmachines, the devices receiving the holders when coming out of one ofthe hackling machines, present them to the screwing mechanism whiletilting them in one direction; after the screwing has been carried outthey tilt them in the other direction to present them to the secondhackling machine. These tilting members are the most important membersof the whole screwing mechanism, in this respect too the well knownsystems are very delicate. In the system comprising pivots a rotatingdevice receives the holder and presents it to an intermediate track orchannel intended to hold the holder to be filled, while a second membertakes the holderup and while performing a pivoting movement transmits itto the other hackling machine. This device comprises a very complicatedset of hinged levers provided at the ends of the two hackling machinescoupled together. These intricate mechanisms placed at the fourtransferring points for the holders must permit of absolute coincidencebetween the pivoting device and the holder carrying track or channel andthis with .an exactness which is absolutely indispensable, otherwisewill occur breaks of parts and interruptions of theservice which arevery costly and take place only too frequently in the well knownautomatic screwing mechanisms.

This invention has for its object todo away with the drawbacks citedabove and to' this effect it provides anovel system of holder combinedwith an ensemble of parts.

As a matter of fact the holder is only an indicate similar partswherever used; Figure I 1 is a perspective view of the holder, the lidbeing shown removed from the bottom plate.

Fig. 12 is a detail view of themechanism illustrated in Fig. 11, but in a raised position adapted toturn the holder. Fig. 13 is a top view of the I mechanism shown in Fig.12, the holder entering the hackling machine. Fig. 14 is a detail viewof the tilting mechanism at the discharge end of the machine. Fig. 15 isa top plan view of the device shown in Fig. 14. Fig. 16 is a detail viewof the tilting mechanism delivering the holder tothe track.

The holder comprises as shown by Fig. 1

a metallic lower or bottom plate 1 provided with a lower tractionaltenon 2 and with staples 13, 13 provided with wedge shaped holes andpositioned at the ends of the plate 7 1. These staples 13, 13 positionedon one side of the bottom plate and their extensions 6, 6 on the otherside serve as guides and notches 3, 3 which correspond to the staples l3and 13 of the bottomplate 1. These staples in order to enable them topenetrate with certainty into the notches 3, 3 have the shape of atrapeze the larger basis of which is situated at their bottom and has alength equal to the length ofthe corresponding notch. The inner surfaceof the lid is like that of the bottom plate provided with an elasticlining or is corrugated or fluted, as at 4. I

In the middle and on the upper surface of the lid 5 is a projection 7the flanges 8', 8 of which serve to offer a hold to the jaws or fingersof the lid raiser which will be de scribed later on. Secured into thehollow 9 .of the extension 7 is a shaft 10 extendingin the longitudinaldirection of the holder. This shaft is slidingly engaged, in order toavoid any accidental shifting, by the half cylindrical tails 11, 11 oftwo locking memhere 12, 12 the saidtails being slid. over each other. Asmall. annular spring p0sitioned in the hollow compensates any wear {andtear that might-occur. These lock bolts or members 12, 12"are wedgeshaped in the direction of their length as clearly shown by Fig. 1 andare sloping down toward the outside. When these lock bolts 12, 12 arepushed outward they engage the identical .wedge shaped staples 13, 13 ofthe bottom plate 1 when the cover is applied to the lat ter. The lockbolts are guided by heels 14, 14 which at the same time limitthemo-vement of the lock bolts by means'of a pin.

The lock bolts 12, 12 are provided with pushing lugs 14, 14 whichreceive in one direction or the other the pushing action of specialmembers (fingers) of the locking or unlocking shoe which will bedescribed later on and which before shifting the lock bolts into theirlocking position first press the lid upon the bottom plate by actingupon its longitudinal edges, the india rubber linings, 4, 4 and thetextile fibers being compressed and acting as elastic cushions. In thisman,-

ner the lock bolts have nearly no strain at. s

all to sustain and serve rather to fix the tightening pressure than toproduce it themselves. i

The advantages of this novel holder are ening action 'or grip which isobtained all along the holder by means of the shoe and is held (orcompleted) by the wedge shaped lock bolts, is surprising. The reason isthat not only this method of producing the tightening is absolutelyreasonable but that, besides due to the total absence of any obstacle onthe area of the holder a perfect distribution of the textile fibers canbe obtained without any objectionable thicker parts and with less carethan before and with two points of bearing instead of a single one. Itresults from these factors that the tightening or gripping action isabsolutely sure at all points of the holder even with a holder twice aslong as those actually known.

The connection of the heads or channels 15, 15 of the two coupledhackling machines 16, 16' is carried out at the ends of the latter (withintercalation of holder tilting devices described later on) by means ofa direct connecting track or channel 17 which is essentially composed oftwo parts curved so as to form quarters of a circle 17 and 17" (Fig. 6)which are preferably connected to each other by means of a straight part17 (Fig. 6). It is clear that if the radius of the curve has been chosenlarger it would be possible to dispense with the straight central part17 The latter is therefore not an essential feature of the invention.This direct curved connecting channel 17 is composed of two parallelpieces 18, 18 (Fig. 3) which are held at a certain distance from I eachother to form a guide slot. In the form shown by the drawings the curveddirect connecting channel contains besides the side members 18, 18 thedevice for producing the advancing of the holder each of which latter isdesignated as a whole by P.

The'mechanical working of the holders takes place in the followingmanner (Fig. 2). Slidingly mounted on the upper part of a hollowframe-work19 which carries the railway or channel 17, is a slide 20adapted to slide vertically and is provided with two arms 21, 21 whichproject above the curved track 17 making the direct connection. The saidvertical sliding movement is produced by the main shaft 22 of one of thehackling machines 16 which shaft drives an intermediate cross shaft 23provided with a crank disk 24 the connecting rod 25 of which passesthrough the hollow framework 19 from the bottom to the top and acts uponthe slide 20. p

In order to allow the work being done properly, the holder P (positionedon the left in Fig. 2) which comes from the second hackling machine mustbe untightened and unlocked while the lid of the holder P (centralholder in Fig. 2) is being raised so that the operator might remove thehackled textile fiber and replace it by non hackled fiber and while atthe same time the holder P (Fig. 2 'on the right hand side) is againtightened and locked. To this end the arms 21 and 21 each carry acylinder 26, 26 in which a hollow sleeve 27, 27 is adapted to slide in avertical direction this sleeve being pushed downward by a powerfulspring 28. In the said sleeve slides in turn a concentrical rod 29 whichis also pressed downward by a spring 30.

The sleeve 27, 27 carries at its lower part a shoe 31, 31 the sidepieces 32, 32 (Fig. 4) of which bear upon the lateral edges of therespective holders when the slide 20 descends and this with the fullstrength of the spring 28 which is compressed as soon as the side piecesof the shoe 31, 31 touch the lid of the holder. The sleeves 27, 27 beingstopped, their lower rod 29 continues descending and the followingoperation then takes place. a

The cross bar 33 with which the lower end of the rod 29 is providedstrikes against the outer arms of two bell crank levers 34, 34 which aremounted at their summits and in a reverse position on shafts 35 whichare supported by the side pieces of the shoe 31. It follows therefromthat the lower arms or fingers 36, 36 of these bell crank levers arebrought toward each other against the action of their respective returnsprings 37, 37 and while bringing the lugs 14, 14 (Fig. 1) of the holderP (Fig. 2) together disengage the lock bolts 12, 12 from their staples13, 13 (Fig. 1). During this time the holder P has been opened so as toallow the operator to remove the hackled textile fiber and to replaceby'non hackled fiber. This is carried out in the following manner: Asseen from Fig. 1, the lid of the holder is provided with a projection 7having flanges 8, 8. When the holders positioned at P slide into theposition P on the track 17 (see later on how they are propelled) theflanges 8, 8 engage (as shown in Fig. 4) from below the hooks 38, 38 ofa pair of jaws 39. These hooks are provided with springs 40, 40 whichbear upon the plate of the lid and thus secure a good hold on thelatter. The pair of jaws 39 are mounted on an arm 41 which oscillateswith a shaft 42 actuated by a connecting rod 43 which is connected withthe slide 20. The timing of the movement is such that when the slide 20descends the pair of jaws 39 and the lid of the holder are rising.

It must be stated that the connecting rod 43 is connected with the shaft42 through the medium of a boX 43 in which the connecting rod 43 slideswith a certain amount of friction (brought about by means of atightening device 43 so that the lid of the holder may be raised butthat the hand of an operator when caught under the descending lid couldnot be injured, the connecting rod sliding in this instance in its boxDuring the same time, the shoe 31 (positioned on theright hand side ofFig. 2) bears with its sidepieces 32, 32 (Fig. 4) on the lid of therecently filled holder P and produces in this holder the desiredtightening. At this moment the rod 29, continuing its descending motionin a manner similar to that what happens for bringing about the openingof the holder at P, strikes against the lower arms 44 of the bell cranklevers which oscillate against their return springs 45, 45 round theirshafts 46, 46 which are secured into the side pieces of the shoe 31. Itfollows therefrom that the lower arms or fingers '47, 47 of these basecrank levers cause the pushing lugs 14, 14 (Fig. 1) of the holder P tomove away from each other and thus lock this holder which had alreadybeen tightened to its full extent. During the following rising motion ofthe slide 20, the left hand shoe 31 and the right hand one 31 rise andleave the holders P and P after having completed their work while thearm 41 and the pair of jaws 39 descend so as to bring down the lid ofthe holder P The guide lugs 6, 6 of the lid 5 (Fig. 1) penetrate intothe notches 3, 3 of the bottom plate 1 and the textile fiber is engagedand held without however being tightened. At this moment, the holdersare advanced toward the right sideon the curved direct connecting track17-. The holder P is replaced by another one coming from the secondhackling machine 16 and is going to take in turn the place of the holderP which substitutes itself to the holder P and so on.

The holder P and those which preceded it advance toward the firsthackling machine 16 (at the right of Fig. 2)- After having passedthrough this hackling machine, they arrive at the back of the pair ofhackling machines where the changing or shifting mentioned in thebeginning of this specification is to take place. Before this changingis performed, a shoe which isv identical tov the shoe 31 produces firstthe loosening and then the unlocking (i. e. the opening of the holderswhich arrive one after the other). After the changing or shifting hastaken place, a shoe which is identical to the shoe 31 first produces thetightening to its full extent and afterward the locking.

The central lifting device for the changing or shifting (see Figs. 3 and5) is shaped differently from the lifting device of the front tighteningdevice (Fig. 2). The jaws 48 carried by an arm 49 and a stationarybracket 50, have their two hooks 51, 51 shaped like two slightlyinclined planes as shown in elevation by the detail view on the righthand. side of Fig. 5, the slope of the said inclines being such that thelid of the unlocked holder, which slides with its flanges 8, 8' (Fig. 1)on the said inclined planes, is just sufficiently lifted, to set the andbearing upon the lower jaw 54 so as to grasp the textile fiber 52 and topullit sufliciently out of the holder that the part of it which has notyet beenhackled does no longer escape the actionof the hackles of thesecond machine This changing or tractional device works as follows: Thebar 55 which carries the upper jaw 53- and is suit ably guided in arms56 of the framework, is suspended from the slide 20 through the mediumof a cable 57 and carries at its lower end a counter-weight 58.. Whenthe slide 20 descends, the weight 58 which is unable to crush the handof a man between the jaws 53, and 54, applies the upper jaw 53 upon thelower jaw 54 which, mounted on a rod 59 adapted to slide with a certainamount of friction at 60, moves downward while offering a certainresistance. When the slide 20 rises again, an arm 61 of the rod 55.strikes against the 'rod 59 and causes it to rise but after the rod 55so as not to hinder the textile fiber which advances with the holder toplace itself under the locking shoe.

This successiveshifting of the holders along I a suitable distance isproduced by a set of detents or dogs 62- (Fig; 2) positioned in the Itrack 17 and which are adapted to move out of the way when movingbackward (toward the left hand side) but remain in'an upright positionwhen advancing to the right. It is during this motion that they meetwith the tenons or lugs 6 (Figs. 1 and 2) of the holders which theyconsequently cause to advance in accordance with the. requirements ofthe operations already described. Each dog 62 is mounted on a smallsliding plate. 63 the edges of which are engaged intoa guide-wayprovided inside the channel or track 17. The smallsliding plates 63 arehingedly connected with each other through the medium of adjustablerods65.

In order to avoid any breaking of parts in case of an obstacle being metwith during the e advancing motion or in caseof something getting out oforder, the set ofdogs 62 1s. 7 driven by a speclal device of wh1ch thefollowing is a specification: one of'the small sliding dogcarryingplates of the set is secured to a Gall chain 66 which is mountedon two pulleys 67. This chain 66 is secured at one end to a sector 68(which a connecting rod secured to theslide 20 causes to oscillate onits shaft 69) and carries at its other end-a coimter-weight' 71. Themovements are timed in such a manner (see drawing) that when the slide20 descends the weight-71 rises and that afterward the weight 71' actsupon the chain of the dogs 62. In this man ner in case of a stop of thedogs, the counter- Weight remains in its lifted condition but 7 nothingis broken as this was often the case until now in the actuating devicesfor the dogs or other carrying devices for the heads or channels of thehackling machines. This simple, with a special dog device for producingthe advancing. But it is clear that at the place where the holders leavethe heads of the hackling machines as well at the place where they enterinto them, it is necessary to provide a tilting device for rotating theholders 90 first in one direction (escape end) and then in the otherdirection (entrance end).

In Fig. 2 is seen on the left hand side the escape end of one of thehackling machines and on the right hand side the entrance end of theother hackling machine. Fig. 3 shows on the left hand side a holdercoming out from the head or channel and on the right hand side a holdertilted and ready to enter the head or, channel. V

The head or channel 72 (Fig. 2 left hand side) which as well knownperforms a rising and descending motion, carries an oscillating lever 73provided with a counter-weight and which when the channel descendsstrikes.

against an abutment 74 secured to the frameworkof the hackling machine16. It follows therefrom that it is tilted over and that an arm 75 withwhich it is provided strikes laterally against the holder coming out onedge from the head 7 2 in such a manner that this holder falls with itstenons 2 into the entrance groove 76 of the curved connecting track(railway) 17 where it is picked up by a dog 62. The said entrance groove76 is integral with the channel 72 of the hackling machine but when thelatter goes down it places itself in the prolongation of the track 17.This is the tilting device of the escape side.

As to the tilting device for the entrance side (Figs. 2 and 3, on theright) it is pro.

vided with a grooveZ'Z the two edges 7 8 and 7 9 of which form theprolongation of the track 17. The channel is adapted to oscillate"around its edge 7 9 which is formed by a when arriving at the end ofthe railway track, is assuming a flat position in the channel of thetilting device positioned at the filling of the hackling machine Acounter-weight 80 which is mounted on the arm 81 has a tendency tocausethe channel '77 to tilt over through the medium of a connecting rod 82but is prevented from doing so as long as the head or channel of thehackling machine is in its lowermost position. hen the head or channelof the hackling machine rises, the counter-weight becomes free andenters into action, causing the channel 77 to tilt over together withthe holder'and places the latter on edge. The holder entering thetilting device pushes the escaping holder in front of it. Then a dog ordetent of the head or channel of the hackling machine engages the holderand carries it on into the hackling machine.

The flax or hemp intended to be used by the filler, is brought near theoperator on a wooden horizontal rectangular board carrying in its centera vertical wooden rod 83. The prepared pieces are piled up cross wise asshown by Fig. 8. The complete stack of fiber forms a heap about 0.80 to1.00 meter high. The filler takes away from this stack the pieces whichare to be introduced into the holders. It results therefrom that littleby little the height of the heap is reduced and that the operator isobliged to stoop down more and more in order to seize the pieces offiber and when he arrives at the last pieces he has to do a very tiringwork stooping down six or seven times each minute to seize the pieces offiber which are at the level of his foot. In order to do away with thistiring operation which makes the operator lose a most valuable time forthe filling of his holders and which forces him sometimes, especiallywhen he is not very well trained, to let pass holders empty, theinventor has devised to place the stack oi: fiber on the head'of a thickclosed tube floating in water or in a liquid which has been renderedaseptic in order to avoid the fermentation after a certain time. Thisfloat 84 is provided with ribs 85 providing for the guiding thereof andrests upon the bottom of the cylindrical reservoir 86 when the stack iscomplete.

By taking pieces of fiber away, the operator' lightens the float 84which rises by and by in proportion to the removal of the pieces. Itfollows from this arrangement that the upper level of the fibers remainsat a constant height and near the hand of the operator and thearrangement described allows the operator to do his work seated withoutfatigue and at a much greater speed.

Such a device is in accord with the re quirements of the rapid workofthe automatic tightening mechanisms and therefore has real technicaladvantages. The appara tus described is placed on the left hand orcording to this invention are set forth in the introduction to thisspecification.
